mysql 6.x 驱动使用 mysql-connector-java 6.x

mysql 的6.x 驱动发布已经有一段时间了，准备从原先的5.1.39更新到6.0.4。

更新 jar

然后启动项目，

Loading class `com.mysql.jdbc.Driver'. This is deprecated. The new driver class is `com.mysql.cj.jdbc.Driver'. The driver is automatically registered via the SPI and manual loading of the driver class is generally unnecessary.
[WARNING] Unable to create initial connections of pool.
java.sql.SQLException: The server time zone value '�й���׼ʱ��' is unrecognized or represents more than one time zone. You must configure either the server or JDBC driver (via the serverTimezone configuration property) to use a more specifc time zone value if you want to utilize time zone support.

Loading class `com.mysql.jdbc.Driver'. This is deprecated. The new driver class is `com.mysql.cj.jdbc.Driver'. The driver is automatically registered via the SPI and manual loading of the driver class is generally unnecessary.

新的驱动类，位置有了变化，修改配置：

把

driver_class=com.mysql.jdbc.Driver

改为：

driver_class=com.mysql.cj.jdbc.Driver

java.sql.SQLException: The server time zone value '�й���׼ʱ��' is unrecognized or represents more than one time zone. You must configure either the server or JDBC driver (via the serverTimezone configuration property) to use a more specifc time zone value if you want to utilize time zone support.

这句话说明必须知道时区：

修改URL配置

jdbc_url=jdbc:mysql://127.0.0.1:3306/rx_shi?serverTimezone=UTC

我完整的URL配置

jdbc:mysql:///rx_shi?serverTimezone=UTC&characterEncoding=utf8&useUnicode=true&useSSL=false

重新启动项目测试，成功启动并且正常增删改查

下面我的完整配置：
